CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Chinese Patent Application No.201310537564.4, filed on Nov. 4, 2013 and Hong Kong Patent ApplicationNo. 13112395.1, filed on Nov. 4, 2013, the entire content of which ishereby incorporated by reference.

FIELD OF THE TECHNOLOGY

The present application is related to a fully spandex weft-knitted clothand production method thereof and a kind of lingerie lining, whichbelongs to textile technology field.

BACKGROUND

In the process of weft-knitting, cotton or fiber is mainly applied,while spandex filament is secondarily applied for producing cloth. Thecloth surface effect is mainly reflected with the specific texture ofcotton or fiber, if certain specialized cloth requires a very highresiliency (such as joining area of lingerie and lining of bra), commoncloth normally cannot satisfy such expectation.

Therefore, inventing a fully spandex weft-knitted cloth and productionmethod thereof to meet the market demand is one of the dilemmas that thepresent field seeks to solve.

SUMMARY

The present application provides a production method of a fully spandexweft-knitted cloth and includes the following steps:

Weft knitting 40 D and/or 70 D spandex filament on a double-sidedknitting machine (also known as the double-sided large circularmachine). The weft-knitting includes needle-containing (tuck) weavingthe spandex filament with the needle of the upper needle dial, at thesame time, needle-containing (tuck) weaving with the needle of the lowerneedle dial, forming needle-containing double-sided stitches. Then,needle (wreathe) weaving the spandex filament with the needle of theupper needle dial while without the needle of the lower needle, andforming upper single-sided stitches. Further, needle (wreathe) weavingthe spandex filament with the needle of the lower needle dial whilewithout the needle of the upper needle dial, forming lower single-sidedstitches and completing a weaving cycle. A fully spandex weft-knittedcloth is obtained by completing one or a plurality of the weavingcycles.

In the production method of the above fully spandex weft-knitted cloth,optionally, the yarn length of the upper single-sided stitches and lowersingle-sided stitches is 12-14 cm/100 G. The yarn length of theneedle-containing double-sided stitches is 14-15.5 cm/100 G.

In the production method of the above fully spandex weft-knitted cloth,optionally, the delayed gap between the needling of the needle of theupper needle dial and the needling of the needle of the lower needledial is three needles.

The present application also provides a fully spandex weft-knittedcloth, which is produced from the production method of the above fullyspandex weft-knitted cloth.

The present application also provides a lingerie lining, which includesthe above fully spandex weft-knitted cloth.

The production method of a fully spandex weft-knitted cloth includes thefollowing steps:

As FIG. 1 illustrates, weft-knitting is performed on the abovedouble-sided large circular knitting machine applying spandex filament.The method of weft-knitting includes: needle-containing (tuck) weavingthe spandex filament with the needle of the upper needle dial, at thesame time, needle-containing (tuck) weaving with the needle of the lowerneedle dial. The delayed gap between the needling of the needle of theupper needle dial and the needling of the needle of the lower needledial is three needles, forming needle-containing double-sided stitches1. Then, needle (wreathe) weaving the spandex filament with the needleof the upper needle dial while the needle of the lower needle dial doesnot perform weaving, forming upper single-sided stitches 2. Further,needle (wreathe) weaving the spandex filament with the needle of thelower needle dial while the needle of the upper needle dial does notperform weaving, and forming lower single-sided stitches 3 andcompleting a weaving cycle. In other word, according to FIG. 1, thestitches are arranged in angularity. The stitches form one weaving cyclein every three molds which include needle-containing double-sidedstitches 1, upper single-sided stitches 2 and lower single-sidedstitches 3. A fully spandex weft-knitted cloth is obtained aftercompleting one or a plurality of weaving cycles.

As the fully spandex weft-knitted cloth in the present applicationapplies spandex with melting and shaping properties for performingweaving, the cloth obtained can possess greater flexibility andfirmness, allowing it to achieve a fitting effect incomparable by otherproducts, and can be added into every kind of lining in clothing toincrease its firmness and flexibility based on different needs.

Gripping (parameter) testing is performed on the cloths obtained thatapplied different raw materials and different weaving methods. Theresult obtained is shown in Table 1. In particular, the warp-knittingapplied is commonly used warp-knitting in the present field. Theweft-knitting applied is weft-knitting in the production method of thepresent application. It can be seen from the data in Table 1, thegripping (parameter) testing result of the fully spandex weft-knittedcloth in the present application far surpassed the testing results ofcloths produced from other raw materials and weaving methods. The fullyspandex weft-knitted cloth in the present application definitelypossesses better flexibility.

Testings on the tensile force, thickness and rollability of the clothsapplied with fully spandex filament and those produced from otherweaving methods are performed. The results obtained are shown in Table2. In particular, the warp-knitting applied is the warp-knittingcommonly used in the present field. The weft-knitting applied isweft-knitting in the production method of the present application. Itcan be seen from the data in Table 2, the testing results of the tensileforce, thickness and rollability of the fully spandex weft-knitted clothin the present application surpass the testing results of the fullyspandex warp-knitted cloth. The fully spandex weft-knitted cloth in thepresent application definitely possesses better flexibility andfirmness.

The production method of the fully spandex weft-knitted cloth in thepresent application revolutionalized the use of raw materials in theweaving production distinguished from traditional practice andinventively applied spandex filaments. No matter whether it is theweft-knitting weaving production, or the textile materials and clothingcapability aspects, the present application is an important and novelbreak-through. The production method in the present application appliesspecialized weaving method, and a fully spandex cloth can be weaved outusing a double sided knitting machine (including rib knitting machine).Since the spandex with melting and shaping properties is applied forweaving, the cloth obtained can possess greater flexibility andfirmness, allowing it to achieve a fitting effect incomparable by otherproducts and can solve the inflexible characteristic of general cottonand fiber cloths due to weaving too densely which would result inloosening and finally causing flabbiness of the cloth surface incapableof achieving firmness. Since the fully spandex weft-knitted cloth in thepresent application possesses the capability of high gripping parameter,it can fit comfortably on the surface of skin and prevent the situationof relocation or fall off of the clothing due to motion of the wearer.Hence, it can be applied to lingerie lining, underwear border, clothingor pant border during weaving of cloths and can be used as a type ofcloth when large flexibility is required and which effect cannot beachieved using fiber and cotton.
